Application filed November 4, 1916. Serial No. 129,603.

To all whom it may concern Be it known that 1, WILLIAM FINKEL- STEIN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Riveting-Machines, of which the following is a specification.

This invention relates to riveting machines, and with regard to the more specific features thereof, to a simple and efficient machine for expediting and improving the process of manufacturing hand bags, satchels and like receptacles.

One of the objects thereof is to provide a riveting machine for automatically performing the operation of riveting the lining, insert and casing of a handbag or satchel in secured relation.

Another object is to provide a riveting machine characterized by a positive and efficient operating quality, ease of operation, and by its compact and durable construction.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in a riveting machine wherein is embodied mechanism for securely positioning pins or rivets in certain portions of a handbag to be bound together, cooperating means to sever superfluous portions of the pins or rivets, and pressing mechanism for forming heads upon the rivets in an efficient and durable manner to complete the riveting of the handbags.

In the accompanying drawings, wherein is shown one of various possible embodiments of the invention,

Figure 1 is a side elevation of the riveting machine, comprising the present invention,

Fig. 2 is an enlarged fragmentary perspective view of the upper portion of the machine,

Fig. 8 is a vertical sectional view of the mechanism disclosed in Fig. 2,

Fig. 4: is an edge view of the machine,

Fig. 5 is an enlarged detail perspective view of the lower extremity of the plunger element,

Fig. 6 is a fragmentary perspective view of portions of a handbag upon which the riveting machine operates.

Similar reference characters refer to similar parts throughout the several views of the drawings.

In order to render clearer certain aims of this invention and the means whereby they are achieved, it may here be noted that hitherto in the art of manufacturing handbags and like receptacles, it has been customary to rivet by hand the outer casing and inner linings thereof, which involves an exceedingly laborious and tedious operation. To satisfactorily accomplish this action the services of skilled workmen are required to perform the same, which, necessarily, adds to the cost of manufacturing the handbags. The present invention provides a machine whereby this riveting operation will be capable of being far more quickly accomplished, and in a superior and excellent manner by relatively inexperienced labor, thereby materially decreasing the cost of production and at the same time improving the general workmanship on the handbags.

To this end, the invention comprises a riveting machine B, primarily operable for use in the above connection, said machine preferably consisting of a circular base 5,. which extends upwardly to form an integral pedestal 6. Bolted to or formed integral with the upper extremity of the pedestal is a curved and angularly extending supporting arm 8, the latter being provided with integral ears 9, in which is pivotally mounted an oscillatory lever 10, said lever embodying an elongated leverage portion 11 and a relatively short plunger operating extremity 12. The outer end of the portion 11 is pivotally connected as at 13 to one end of a connecting rod 14, the latter having its other extremity pivotally secured as at 15 to an attenuated extremity 16 of a foot operated pedal 17. The pedal is pivotally connected as at 18 to the lower end of member 16 and a coil spring 18 has its terminals secured to the pedal 17 and to the base 5 so as to re tain the pedal in a normal, inactive position. By manually depressing the pedal 17 the same will be oscillated about its fixed pivotal point 18, which will impart synchronous movement to the lever 10, through the medium of the cooperating connecting rod 14. The oscillation of the lever 10" efiects the operation of the machine in a manner to be presently disclosed. g

Secured by means of a yoke connection 20 a to the extremity 12 of the lever 10 is a rivet forming plunger 21, which operates in a vertical guide opening 22 formed in the outer extremity of the arm 8. Thus upon depressing the pedal 17 the plunger 21 will be forced downwardly so as to effect the operation of the machine B. The lower 'extremity of the plunger 21 is formed to provide an operating head 24, in which is provided a slot Pivotally mounted, as at 26, within the slot 25 is a swinging cutter arm 27, which is provided with an elongated extremity 28, protruding inwardly toward the pedestal 6. A pin 29 fixed upon the outer extremity 28 operates in a slot 30 formed in the lower yoked end of a cutter operating link 31, the latter being pivotally connected as at 32 to the lever 10, so that after the extremity 11 of the lever 10 has been moved upwardly a predetermined dis- P tance, the cutter arm 27 will be oscillated,

as will be clearly understood. The operation of the link 31 upon the arm 27 may be further regulated through the services of a set screw 33, threadedly connected with the link 31, so as to adjust the operative relation between the link 31 and the arm 27, if such adjustment should be found necessary. The forward extremity of the arm is pro vided with an angularly disposed offset portion 34:, in which is formed a similarly extending threaded bore 35, the latter being operable to receive an adjustable threaded cutting element 36, located on an angle with respect to the plunger 31 and capable of having its relation with the plunger conveniently varied. A locking nut 36" is utilized to retain the element 36 locked in its vari ous adjusted positions. A beveled knife or cutting edge 37 is formed on the inner extremity of the element 36 and is utilized for the purpose of severing superfluous portion of securing rivets utilized in the manufacture of handbags, as will be more fully explained.

A bracket 38 is fixed to the pedestal 6 at a vposition beneath the arm 8, and has bolted or otherwise secured thereto ail-offset arm 39 of a spring holding casing 39, the latter extending substantially parallel to the pedestal 6 and is also disposed beneath the arm'8. Positioned within the casing 39 is a strong compression spring 40, which has its upper terminal pressing upon the lower end of a depending anvil rod 41, while the lower terminal of the spring is positioned upon an adjustable screw 42, threaded into the casing 39. By adjusting the screw 4.2, the strength of the spring may be conveniently controlled. The rod 41 is provided with a fixed stud 13, operating in an elongated slot 1% formed in the wall of the casing 39", said stud being utilized to control and limit the movement of the rod 41.

Fixed to the upper end of the rod 41 and adjustable thereon is an anvil or pressing block 44:, the latter being provided with an operating extremity a5 disposed in relative alinement with the vertically movable head 24. The block is employed to receive the portions of a handbag 46, or other receptacle, to be riveted, that is, the outer casing 47 thereof, the internal lining a8 and the insert or reinforcing strip 19. These elements are united by means of headed pins 50, which are acted upon by the machine to rivet in secured relation the aforementioned parts of the handbag, preferably along the mouth edges of the latter. The extremities of the pins 50 are manually pressed, in spaced relation, through the casing 17 and its associated parts, so that the enlarged heads 51 thereof will be located on the outside of the bag, while the shanks 52 thereof will extend inwardly of the same. After the bag e6 has been thus prepared it is subjected to the action of the riveting machine, which is designed, through mechanism previously described, to cut off the superfluous portions of the shank 52, to press the casing M, the lining 48 and the insert 4L9 into close relation, and to finally form rivet heads upon the ends of the shanks 52, so as to retain the elements of the hand bag in their closely related position, so that their accidental disengagement will be rendered impossible.

To accomplish these results, the mouth edge of the hand bag 46 is placed upon the anvil 11 with the shanks 52 of the rivets extending upwardly in the manner shown, the bag being retained in this position by the operator of the machine. lVhen the bag is thus positioned, the operator depresses the pedal 17 with his foot, and by the mechanism described the head 21 of the plunger 21 will be brought down to bear upon the insert 19 of the handbag, thus pressing the 00- operating elements associated with the insert together and simultaneously pressing the head 51 of a rivet into close contact with the outer casing 47. By continuing to press the pedal 17, the plunger 21, through the intervening bag 16, will press the anvil 4i downwardly, overcoming the pressure exerted by the spring 4:0. This continued movement results in the operation of the cutter arm 27, the latter being forced to operate by reason of the fact that the pin 29 thereof is engaged by set screw 33 in the lower end of the slot 30 in the upwardly moving link 31. When the arm 27 is oscillated, the knife edge 37 of the cutting element 36 will be forced into engagementwith the extended shank of the rivet 50, so as to sever thesuperfiuous part thereof from the body of the rivet.

The cutting of the shank 52 is facilitated by the peculiar construction of-the operating head 24 of the plunger 21, which in plan,

is substantially L-shaped, that is, provided with perpendicularly disposed walls 55 and .After the unnecessary part of the rivet or pin 50 has been removed, and the elements of the handbag 46 pressed together, the plunger 21 is permitted to again resume its normal position, by permitting the pedal 17 to respond to the action of the coiled spring 19, this action also permitting the anvil 44 to return to its normal position. In order to complete the operation of forming a head upon the severed end of the rivet 50 a revolving locking plate 57, pivoted as at 58 upon the spring casing 39 is oscillated to a point surrounding the rod 41 and interposed between the anvil 44 and the casing 39, so that when the plunger 21 is again moved downwardly, the anvil will not be lowered by its operation. After the anvil has been thus locked, the handbag is placed thereon, in the same manner as previously described, with the remaining portion of the shank 52 extending upwardly toward the plunger 21, then upon again depressing the pedal 17, the head 24 will be forced downwardly, as will be clearly understood, to engage with the end of the shank 52, this feature being assured by providing the head 24 with a depression 58 for the reception of the said shank. Thus it will be apparent that by reason of the immovable anvil 44 the plunger will press the end of the rivet and will flatten the same to form a head, which is pressed flush with the insert 49, this enlargement of the shank 52 will effectively lock the several parts of the handbag together.

The L-shaped head 24 of the plunger, as will be noted, has several functions; the first is to press the lining, casing and insert of a handbag into close relation; to insure the passage of the rivet 50 therethrough, so as to be in position to be operated upon by the cutting element; to serve as a base to facilitate the cutting operation of the ele ment 36; and finally, to form a flattened rivet head upon the shanks of the rivets. These results are accomplished by two operations of the pedal 17. The first oper ation is to sever the superfluous parts of the rivets, and the second is to form heads thereon. It will be further noted that when the locking plate 57 is employed to prevent movement of part of the anvil 44, it will prevent the cutting arm from coming into operation, inasmuch as it limits the movement of the plunger 21. The movements of the several movable elements of the machine may be readily controlled or regulated by the adjustable elements shown, so that their relative operations may be conveniently timed.

It will thus be seen that there is provided mechanism in which the objects of this in vention are achieved and all of the advantageous features above mentioned, are,

among others present. The machine is positive in operation, of few parts and simple construction. The parts are so disposed as to prevent crowding and yet are positively and efliciently driven from a common source of power. The several changes of relation are accomplished with a minimum of time and labor and when the parts are once set the mechanism is of such character as to insure against slipping, and thus rendering the action of the entire machine thoroughly reliable.
